ABSTRACT. This research makes conceptual and methodological contributions to the complex, interactive biological processes that influence personality, the development and ongoing function of cognitive processes and brain systems involved in intelligence, the distinction between impulse and restraint in behavior, and the evolved psychological mechanisms that comprise the structure of human nature. The theory that I shall seek to elaborate here puts considerable emphasis on the causal bases of personality, the prospective relation between childhood personality and adult health outcomes, the role of personality traits in determining economic outcomes, and the neuropsychology of human personality. pp. 134–139
